Is it necessary for women to wear izaar (pants) if they are donning below ankle-length dresses?

Answer

Yes, it is necessary. There is a special reward for them for wearing pants despite the dress covering their bodies thoroughly. Rasulullah (sallallahu alayhi wasallam) said: "Allah has mercy on those women who wear pants." 'Pants' here do not mean wearing pants in the style of the Sudanese woman who was recently convicted and sentenced for her western style lewd pants. The Muslim female's pants is fully concealed under her long dress. It provides greater hijaab.
